i don't see anything wrong with the package doing both, but i can't
comment on an "official" method.

sometimes it's appropriate (when the binaries are 1 or very few) to
make a wrapper that adds the path before invocation.

the other option (i think firefox does something like this) is to add
the path and re-export from an /etc/profile.d/ script, which would run
once at login.  if you look in that directory you will see similar
mods to the environment by packages.
